One thing you do notice with Walcott on instead of Nasri is just how good a player Nasri is, brilliant overall talent - great going forward, two footed, brilliant dribbler, and bothers to track back and throw an assist (Chamakh's goal would probably 9 times out of 10 would have been a shot by the player in Nasri's position).
Yes, Walcott is great at speed, but he's pretty selfish, had a great chance for a playing in Wilshere on against the keeper and didn't seem to see it, I agree he's been injured, but he needs to do something to get that fluency as you can't keep playing on blistering pace into your late 20s.
Nice goal by Eduardo!
EDIT: Also there was another poster mentioning how Denilson is "comparable" to Carrick for Arsenal, with that being a disservice to Carrick. On this evidence he does read the game decently, we'll have to see how he improves over the next couple of seasons if he's going to truly be our version of Mikel with a bit more all round passing ability.
